AIS CLI (command-line interface) is intended to easily control and monitor every aspect of the AIS cluster life-cycle. In addition, CLI provides dataset management commands, commands to read and write data, and more.

Getting Started

To build CLI from source, run the following two steps:

$ make cli			# 1. build CLI binary and install it into your `$GOPATH/bin` directory
$ make cli-autocompletions	# 2. install CLI autocompletions (Bash and/or Zsh)

Alternatively, install directly from GitHub:

For example, the following command extracts CLI binary to the specified destination and, secondly, installs bash autocompletions:

$ ./deploy/scripts/ --dstdir /tmp/www --completions

For more usage options, run: ./deploy/scripts/ --help

You can also install bash and/or zsh autocompletions separately at any (later) time:

To uninstall autocompletions, follow the generated prompts, or simply run bash autocomplete/

Please note: using CLI with autocompletions enabled is strongly recommended.

Once installed, you should be able to start by running ais <TAB-TAB>, selecting one of the available (completion) options, and repeating until the command is ready to be entered.

TL;DR: see section CLI reference below to quickly locate useful commands. There’s also a (structured as a reference) list of CLI resources with numerous examples and usage guides that we constantly keep updating.

TIP: when starting with AIS, ais search command may be especially handy. It will list all possible variations of a command you are maybe looking for - by exact match, synonym, or regex.

The rest of the README assumes that user’s PATH environment variable contains $GOPATH/bin directory. Run export PATH=$PATH:$GOPATH/bin if this is not the case. You can find more about $GOPATH environment here.

CLI Reference

Command Use Case
ais help All top-level commands and brief descriptions; version and build; general usage guidelines.
ais advanced Special commands for developers and advanced usage.
ais alias User-defined command aliases.
ais archive Read, write, and list archives (i.e., objects formatted as TAR, TGZ, ZIP, etc.)
ais auth Add/remove/show users, manage user roles, manage access to remote clusters.
ais bucket Create/destroy buckets, list bucket’s content, show existing buckets and their properties.
ais cluster Monitor and manage AIS cluster: add/remove nodes, change primary gateway, etc.
ais config Set local/global AIS cluster configurations.
ais etl Execute custom transformations on objects.
ais job Query and manage jobs (aka eXtended actions or xactions).
ais object PUT and GET (write and read), APPEND, archive, concat, list (buckets, objects), move, evict, promote, ...
ais search Search ais commands.
ais show Monitor anything and everything: performance (all aspects), buckets, jobs, remote clusters, and more.
ais storage Show capacity usage on a per bucket basis (num objects and sizes), attach/detach mountpaths (disks).

Note: In CLI docs, the terms “xaction” and “job” are used interchangeably.

CLI Config


  • CLI configuration directory: $HOME/.config/ais/cli
  • CLI configuration filename: cli.json

For the most updated system filenames and configuration directories, please see fname/fname.go source.

When used the very first time, or if the $HOME/.config/ais/cli/cli.json does not exist, the latter will be created with default parameters:

  "cluster": {
    "url": "",
    "default_ais_host": "",
    "default_docker_host": "",
    "skip_verify_crt": false
  "timeout": {
    "tcp_timeout": "60s",
    "http_timeout": "0s"
  "auth": {
    "url": ""
  "aliases": {
    "get": "object get",
    "ls": "bucket ls",
    "put": "object put"
  "default_provider": "ais"

If you update config via ais config cli set command (or even simply change the config file) the next time CLI will use updated values.

First steps

To get the list of supported commands, run:

$ ais help

Alternatively, you could start making use of auto-completions by typing ais and pressing TAB key two times in a row.

To check if the CLI can correctly contact the cluster and to get cluster status, run following command:

$ ais show cluster

Global options

Besides a set of options specific for each command, AIS CLI provides global options:

  • --no-color - by default AIS CLI displays messages with colors (e.g, errors are printed in red color). Colors are automatically disabled if CLI output is redirected or environment variable TERM=dumb is set. To disable colors in other cases, pass --no-color to the application.

Please note that the place of a global options in the command line is fixed. Global options must follow the application name directly. At the same time, the location of a command-specific option is arbitrary: you can put them anywhere. Examples:

$ # Correct usage of global and command-specific options.
$ ais --no-color ls ais://bck --props all
$ ais --no-color ls --props all ais://bck
$ # Incorrect usage of a global option.
$ ais ls ais://bck --props all --no-color

Backend Provider

The syntax provider://BUCKET_NAME (referred to as BUCKET in help messages) works across all commands. For more details, please refer to each specific command’s documentation. provider:// can be omitted if the default_provider config value is set (in such case the config value will be used implicitly).

Supported backend providers currently include:

  • ais:// - AIStore provider
  • aws:// or s3:// - Amazon Web Services
  • azure:// or az:// - Azure Blob Storage
  • gcp:// or gs:// - Google Cloud Storage
  • hdfs:// - HDFS Storage
  • ht:// - HTTP(S) datasets
